Frequently Asked Questions
Comparing the price first, a 5-star non-inverter AC is cheaper than an inverter AC. The compressor efficiency of the inverter AC is high as compared to the non-inverter 5-star AC. The speed of the compressor is fixed in a non-inverter AC and inverter ACs feature variable speed compressors. The power consumption in inverter AC is less while starting whereas in non-inverter AC it is high. As far as the noise level is concerned it is high in non-inverter AC as compared to inverter AC. The cooling liquid and cooling efficiency are more streamlined in 5 star AC while inverter AC depends on the model and brand. Due to the variable nature of the compressor in inverter AC and its cooling functionality, the power consumption is lower.
If you would like to learn more about why an inverter AC is better than a non-inverter AC then we recommend checking out our detailed post on Inverter AC Vs Non-Inverter AC.
The AC inverter concept does not mean that it runs on a battery backup which will function during any power failure or power cut off. It requires electricity to run Inverter AC. So it is a wrong notion that Inverter AC can function without electricity. The main function of an inverter AC is to reset the compressor once the cooling of the room temperature reaches the desired level. Like in the case of regular ACs, the compressor is not turned on or off and instead, the compressor speed is reduced and increased as per the room temperature. This is done through the microprocessor digital circuits. The main objective is that sudden voltage jet spikes can be avoided which in other cases might reduce the life of the compressor and lead to higher power consumption.
There are of course many brands in the market which are selling the feature of an “inbuilt stabilizer”. This needs to be taken with a pinch of salt and if closely observed there is almost every time a caution statement that goes along with it. The advantage of having a stabilizer is that it helps in running the voltage in the optimal range even if the supply of power is fluctuating. Normally the fluctuation does not deviate too much. For inverter AC, the range is between 160 to 245 Volts. Normally the voltage comes in this range only. A stabilizer is required only if it falls beyond this range. Using a stabilizer will protect the components of an AC and it is true for any electrical device. Having said this, an inbuilt stabilizer does indeed bring a good measure of fluctuation controls.
Having said that, we would still recommend installing an external voltage stabilizer just to avoid any chances of damage to AC.
There is no exact size defined for a 1-ton ac but it is generally expected not to exceed beyond 12 feet * 12 feet which are the maximum recommended size. Normally most of the brands recommend 1-ton AC to be used for a room with areas between the range of 90 and 110 square feet. There are other things that can be but not necessarily need to be taken into consideration like which floor of the building the room is situated? The number of doors and windows in the room etc. Most of the brands have their own tonnage calculator methods which are by and large similar.
If you are not living on the top floor or the room is not getting too much direct sunlight then in most cases a 1-ton ac is sufficient for cooling an area of up to 120 sq. ft.
Before 2016 there was no system in place for the star rating of inverter ACs. But, since the year 2016, the Bureau of Energy Efficiency (BEE) has started rating of inverter ACs also. This was due to the fact that in spite of superior and power saving performance Inverter AC’s had a constraint over star rated non-inverter ACs in the general consumer thinking. In the year 2018, the BEE has merged the ratings of the inverter and non-inverter AC’s. At present all inverter AC’s have 3, 4 and 5-star ratings.
